Answer:
Plasma membrane forms a stable barrier.
Step-by-step explanation:
- Cell membrane is a thin flexible membrane, it is present in every living cell.
- It is also known as plasma membrane or cytoplasmic membrane. This membrane is selectively permeable to organic molecules and ions. It is made up of proteins and lipids
- This membrane forms a stable barrier between two aqueous compartments i.e. to separate the inside of cells from the outside.
- Cell membrane separates the cytoplasm of the cell from the surroundings.
Result: Plasma membrane act as a barrier to protect the cell content from the surroundings.
